    When checking for bzr repo, only use quick checks (closes bgo#641624)
    
    'bzr check' checks the working tree, branch and repository. Since we're
    only running this to verify that the directory is in fact a bzr repo,
    we don't really need the full suite of checks. This commit changes to
    just performing tree and branch checks, for a considerable speedup on
    large repositories.
    
    Patch from Tristan Hill.
